Heat transfer crisis during liquid nitrogen cooling of high temperature superconductor

Study of Cryogenic Film Boiling in the Presence of External Electric Field Using a Variant of Volume of Fluid-Based Interface Tracking Algorithm

“…Several researchers studied film boiling for water and many refrigerants experimentally and through computer simulations. − It was observed that interfacial instability plays a significant role in film boiling heat transfer. In such cases, it is generally guided by Rayleigh–Taylor instability.…”

Effect of orientation of the heat-release surface on heat transfer to liquid nitrogen

“…A large number of various factors (pressure, underheating to saturation temperature, geometrical and thermal characteristics of the heat-release surface, orientation in the gravitational field, and others) have an effect on the heat exchange characteristics in liquid nitrogen. A large number of data on heat exchange during nitrogen boiling on various heating surfaces are collected to the present time [1]; however, such knowledge on boiling on substrates used in the production of HTSC-2 tapes are almost not presented in the literature. In this case, reliable data on heat exchange to liquid nitrogen from HTSC-2 substrates can be obtained only by experimental studies.…”

“…Currently, there are no physical models which would yield the functional dependence α(ϕ). Only few works [1,5,6] are known, in which the effect of the tilt angle on the heat transfer during boiling on plane heaters with one-sided cooling was experimentally studied.…”
